Abstract
A method of determining whether a sample or a control has been applied to an instrument for measuring coagulation of a fluid by optically detecting when the fluid that has been applied to the instrument has passed a first and a second points, determining the flow time for the fluid between the two points, establishing a time threshold, and the flow time to the threshold to determining if the fluid is a sample or a control.
